Is the cutting method in steel S355ML cutting comparable

In terms of service, our service is a "one-stop" way of working. We have our own steel S355ML processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as steel S355ML cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Q690D steel material is a low-alloy ultra-high strength steel grade. Standard: GB/T 3077. The hardenability of steel is high, and the critical hardenable diameter in oil is 60mm (96% martensite). After quenching and tempering, steel can obtain high strength, and has certain toughness, and can be processed into shape. But cold deformation plasticity and weldability are low.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. steel S355ML, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

The alloy wear-resistant layer of steel S355ML, wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is fibrous distribution, and the fiber direction is vertical to the surface. The alloy carbide has strong stability at high temperature, maintains high hardness, and has good oxidation resistance. It can be used normally within 500℃.

JIS SS490 structural steel angle description: Item: SS490 angle steel. Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. steel S355ML Surface: black or galvanized. Length: 6 m, 9 m, 12 m or per your request. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. steel S355ML Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 mm to 250 × 90 mm. steel S355ML Thickness:3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled steel S355ML plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive steel S355ML industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

Our quality and service commitment: steel S355ML product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
